Rewrote .agents/domains/knowledge/schema.md and .agents/shared/llm-wiki.md
which described the deleted Python substrate (bin/homelab, oikos/cards/,
oikos/ledger.py, root inventory.yaml, knowledge/sources/, get_page/
search_docs MCP tools). Now reflect ADR 0003: Postgres DB is the single
source of truth for structured data and narrative knowledge; seeds/*.yaml
are bootstrap+DR manifests (content-hashed via seed_versions); archive/
knowledge/ is the frozen legacy wiki; MCP search_knowledge/get_entity_
knowledge replace get_page/search_docs.
Swept substrate refs in .agents/shared/{writing-style,page-templates}.md
and .agents/domains/operations/schema.md: bare inventory.yaml ->
seeds/inventory.yaml; knowledge/sources/ -> archive/knowledge/sources/
(historical); get_changelog/oikos/ledger.py -> DB audit trail / structured
document changelog field; HERMES -> Nomos.
Root inventory.yaml (618-line Python-era file superseded 2026-07-07 by
seeds/inventory.yaml) replaced with a deprecation stub pointing to the seed
and DB. Kept as a stub rather than deleted because AGENTS.md §1/§2 still
point clients at /opt/homelab-context/inventory.yaml; full on-client path
reconciliation deferred to R13.
Flagged export gap: oikos export regenerates seeds/{ontology,inventory,
policy}.yaml but NOT seeds/knowledge.yaml — API-added knowledge lives only
in the DB until hand-edited into the seed.
VERSION 0.7.7 -> 0.7.8. Plan R5 marked done.

# Operations domain — schema
|
|
|
|
The operations domain holds the procedural and time-stamped documentation: runbooks (repeatable
|
|
procedures), investigations (incident evidence), and plans (design docs for non-trivial work). It
|
|
follows [writing-style](../../shared/writing-style.md); runbooks and plans use the imperative voice
|
|
exception.
|
|
|
|
Where each kind lives: runbooks are skills under [`.agents/skills/`](../../skills/); operator
|
|
reference (command cheatsheet, enrollment, Nomos agent) lives in
|
|
[`.agents/operations/`](../../operations/); investigations are `investigation` entities in the DB
|
|
(historically `archive/knowledge/sources/investigations/`); plans stay in the repo-root `plans/`
|
|
folder (below).
|
|
|
|
## Plans always live in `plans/`
|
|
|
|
**Any plan or design doc for the Homelab is written into the repo `plans/` folder as
|
|
`plans/YYYY-MM-DD-slug.md` — never a scratch path, an agent-private plan location, or a chat
|
|
message.** An agent drafting a plan:
|
|
|
|
1. Writes the file under `plans/` using the plan template in [page-templates.md](../../shared/page-templates.md).
|
|
2. Lists it in `plans/index.md`.
|
|
3. On completion, moves it to `plans/done/` and updates the index status.
|
|
|
|
This is the single source for homelab design intent; keeping it in-repo means the plan is
|
|
versioned, reviewable, and reachable by MCP `search_knowledge` like any other doc.
|
|
|
|
## Runbooks
|
|
|
|
Repeatable procedures are skills — one folder per skill at `.agents/skills/<name>/SKILL.md`, with
|
|
YAML front-matter that the Oikos policy and lifecycle machinery reads:
|
|
|
|
```yaml
|
|
---
|
|
name: <name>
|
|
risk_class: read_only | reversible_low | config_mutation | destructive
|
|
inputs: [<param>, ...]
|
|
verification: "<shell expression that proves success>"
|
|
docs_update_checklist: [<doc artifacts to update>]
|
|
transition: "<from> -> <to>" # only for lifecycle runbooks
|
|
---
|
|
```
|
|
|
|
`risk_class` values and the lifecycle `transition` states must match
|
|
[`seeds/policy.yaml`](../../../seeds/policy.yaml) and [`seeds/ontology.yaml`](../../../seeds/ontology.yaml).
|
|
|
|
## Investigations
|
|
|
|
Incident records are `investigation` entities in the DB, linked to the entities they implicate via
|
|
`about` edges. They are **evidence sources** — written once at incident time, then back-linked from
|
|
the changelogs of the nodes they implicate. Sections: `## Summary`, `## Timeline`, `## Root cause`,
|
|
`## Mitigations applied`, `## Open questions`. The legacy file-based investigations live at
|
|
`archive/knowledge/sources/investigations/` (frozen 2026-07-07); new investigations go in the DB.
|
|
|
|
## The operations log
|
|
|
|
`plans/log.md` is the append-only record of documentation operations on plans
|
|
(`## [YYYY-MM-DD] <op> | <summary>`), distinct from the DB audit trail. The legacy
|
|
`archive/knowledge/log.md` is frozen with the rest of the archived wiki.
